A condensation device 3 is fixedly connected inside the range hood duct 2. The condensation device 3 includes an internal pipe 301, a mounting bracket 302, a spiral pipe 303, a funnel 304, and a guide groove 305. A collection mechanism 5 is fixedly connected to one side of the range hood duct 2. A first collection box 6 is slidably connected inside the collection mechanism 5. The internal pipe 301, the range hood duct 2, and the collection mechanism 5 all have the same opening 4. A circulating water pump 7 is fixedly connected to the water inlet end of the spiral pipe 303. A cooling device 9 is fixedly connected to the outlet end of the spiral pipe 303. A connecting pipe 8 is fixedly connected between the cooling device 9 and the circulating water pump 7. The cooling device 9 includes a copper ring 901 and a semiconductor ring 902. By setting up the spiral pipe 303, the circulating water pump 7, the cooling device 9, and the collection mechanism 5, the water temperature inside the pipe is reduced by activating the cooling device 9. After passing through the action of the circulating water pump 7, the cold water enters the interior of the spiral pipe 303 to cool the air. The condensate obtained from the cooling of the air, carrying oil, is collected by the collection mechanism 5, realizing the collection of oil in the fumes, avoiding direct discharge to the outside, protecting the environment, and realizing the secondary utilization of oil in the fumes.

[0025] The range hood duct 2 is internally fixedly connected to three filter devices 10. Each filter device 10 includes a frame 101, a detachable plate 102, and a filter screen 103. By setting up three filter devices 10 inside the range hood duct 2, multiple filtrations of toxic and harmful dust in the fumes are achieved, effectively reducing the dust content in the exhaust fumes and protecting the environment. At the same time, the detachable structure allows for quick replacement of the filter screen 103, which is convenient and efficient.

[0026] The upper and lower ends of the built-in pipe 301 are fixedly connected to the mounting bracket 302. The spiral pipe 303 is located between the inner and outer walls of the built-in pipe 301. The funnel 304 is fixedly connected to the inside of the built-in pipe 301. The guide groove 305 is fixedly connected to one side of the inside of the built-in pipe 301. The funnel 304 is located below the spiral pipe 303. The guide groove 305 is located below the funnel 304. The groove surface of the guide groove 305 is connected to the opening 4 and kept parallel. The opening 4 is located above the first collection box 6. The outer surface of the copper ring 901 is fixedly connected to the semiconductor ring 902. The cooling device 9 and the circulating water pump 7 are both fixedly connected to the outer surface of the range hood pipe 2.

[0027] The detachable plate 102 is slidably connected to the inside of the frame 101. The inside of the detachable plate 102 is fixedly connected to the filter screen 103. An external fan 11 is fixedly connected to the other end of the range hood duct 2. A smoke inlet 12 is fixedly connected to the lower side of the range hood body 1. A second collection box 13 is slidably connected to the lower end of the smoke inlet 12. By setting the detachable plate 102, the filter screen 103 can be quickly removed from the filter device 10, realizing the replacement of the filter screen 103, improving the disassembly efficiency, and making it convenient, quick and efficient. The external fan 11 can assist the range hood in quickly exhausting the fumes outdoors, reducing the load on the range hood and improving its working efficiency. Setting the second collection box 13 at the lower end of the smoke inlet 12 is a traditional way for range hoods to collect fumes. By setting a narrow gap inside the range hood, the air flow speed can be accelerated, causing the air temperature to drop. The water in the air will liquefy and be collected by the second collection box 13 along with the oil, realizing the micro-processing of the fumes.

[0028] Working principle: When in use, the power is turned on. When treating oil fumes in the air, the circulating water pump 7 is started. The circulating water pump 7 transports the hot water generated by the heat exchange between the spiral pipe 303 and the air through the connecting pipe 8 to the cooling device 9. Then, the semiconductor ring 902 is started. The cold surface of the semiconductor ring 902 absorbs the heat of the hot water inside through the copper ring 901, causing the hot water temperature to drop and become cold water. It returns to the spiral pipe 303 to exchange heat with the air again, realizing the continuous reduction of air temperature. The water in the air liquefies as the temperature drops. During the liquefaction process, the water and oil stick to the surface of the built-in pipe 301. As the weight increases, it falls down along the funnel 304 and the guide groove 305 through the opening 4 into the second collection box 13, realizing the collection of oil in the oil fumes. Then, through the action of the range hood and the external fan 11, the oil fumes pass through three filter devices 10. The filter screen 103 filters the dust in the oil fumes before being discharged outdoors. Through the above two processes, the oil and dust in the oil fumes are removed.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
